Tillage And Fallow Effects On Selected Soil Quality Characteristics Of Former Conservation Reserve Program Sites, John E. Gilley, John W. Doran, Bahman Eghball

Biological Systems Engineering: Papers and Publications

Tillage and fallow have been suggested as management options for converting Conservation Reserve Program (CRP) areas to cropland. This study was conducted to measure selected soil quality characteristics of former CRP sites in Mississippi, Nebraska, and South Dakota that were tilled and then left fallow for 21 or 22 months. Soil samples from depth intervals of 0-7.6 cm and 0-30.5 cm were collected for laboratory assessment of the following soil quality indicators: bulk density, EC, pH, total C, organic C, total N, NO₃-N, NH₄-N, PO₄-P, biomass C, biomass N, anaerobic NH₄-N, lab …
